CLOSURE FOR CONTAINERS.

Application filed February Our invention relates to cans for shipping paints and other substances which are .required to be shipped in sealed containers, and more particularly to the closure for such containers.

The object of the improvement is to provide a sheet metal container having a circumferential, inwardly disposed, convex seat for a collapsible packing ring or gasket near its upper open end, the cover having a peripheral flange adapted to fit within said circumferential seat, and provided with a reinforced, peripheral head for compressing the gasket upon said seat, spaced tongues being formed at the upper, open end of the container and adapted to be bent over the per'ipheral edge of the cover in closed position compressing the gasket between the bead of the cover and the circumferential seat in the container, while the peripheral flange upon the cover contacts with the circumferential seat in the container, thus effectually sealing the container.

An embodiment of the invention is illustrated in the accompanying drawing, in which 7.

Figure l is a side elevation of the improved container, showing the cover in the sealed position, parts being broken in section;

Fig. 2, a fragmentary, perspective view of the same, and

Fig. 3, a fragmentary sectional view show-- ing the cover in position before the tongues have been bent down and the gasket compressed.

Similar numerals of reference indicate corresponding parts throughout the drawing.

The container, or can, formed of sheet metal and the body portion thereof may be cylindrical and of any usual and well known construction to produce a liquid tight container.

The bottom 2 is permanently secured, at its peripheral edge, to one end of the body 1 to form a tight joint. Near its other end the integral, inwardly disposed, convex, circumferential seat 3, which may be inclined downward and outward as at 4 and provided with'the convex seat or shoulder 5 at its top side.

A cylindric flange 6 is formed above this circumferential seat and provided at its exto hold the same 1 is preferably 10, 1926. Serial No. 87,339.

tremity with a series of spaced integral tongues 7.

The cover or top 8, adapted to close the open end of the container, is provided with the peripheral, upstanding flange 9 adapted to fit snugly within the circumferential seat 3.

An outturned, wired bead 10, adapted to fit within'the annular flange 6, is formed at the peripheral edge of the flange 9.

In applying the cover or top to the container a compressible gasket or packing ring 11 is placed upon the circumferential seat or shoulder 5, and the cover 3 is then placed in the position shown in Fig. 3, with the flange 9 extended downward through the gasket and the bead 1O resting upon the gasket. The tongues 7 are then bent, downward and inward, over the peripheral edge of the cover, compressing the gasket, as shown in Figs. 1 and 2, and forcing the cover downward into the position shown in said figures, the flange 9 thereof contacting with the inner edge of the convex seat 3 upon the container.

The cover is thus retained in position upon the container the gasket being compressed and filling the entire space between the bead the cover engaging the convex seat 3 of the container and thus effectually sealing the closure.

By forming the seat 3 convex or in a ra dius,

from the point of juncture with the flange (3 to the straight portion 4, the space in which the gasket is received is substantially wedge shaped, producing acalking action upon the gasket when pressure is applied upon the cover or bead thereof, and it will be obvious that any increased or addi tional pressure or blows upon this bead will only tend to more tightly compress or wedge the-gasket providing a tighter seal.

We claim I 1. A container having a circumferential, inwardly disposed, convex seatadjacent to oneend, tongues upon the extreme end of the container, and a cover adapted to be positioned within the open end of the container,

a peripheral flange upon the cover adapted to frictionallyfit within said convexseat, a

bead upon said flange and a gasket adapted to be compressed between the seat and bead, said tongues being adapted to be bent m- Wardly over said flange to retain the cover in position.

2. A container having a circumferential, inwardly disposed, convex seat adjacent to one end, tongues upon the extreme end of the container, and a cover adapted to be positioned within the open end of the container, a peripheral. flange upon the cover adapted to frictionally fit within said convex seat, a bead upon said flange adapted to fit within the container adjacent to said seat and a gasket adapted to be compressed between the seat and bead, said tongues being adapted to be bent inwardly over said flange to retain the cover in position.

3. A container having a circumferential, inwardly disposed, convex seat adjacent to one end, said seat having an arcuate shoulder at its upper side and being inclined downward and outward, tongues upon the extreme end of the container, and a cover adapted to be positioned within the open end of the container, a peripheral flange upon the cover adapted to frictionally fit within said seat, bead upon said flange and a gasket adapted to be compressed between the seat and head, said tongues being adapted to be bent inwardly over said flange't-o retain the cover in position.

4. A container having a circumferential convex seat near one end, and a cover adapted to be positioned within the open end of the container, a peripheral flange upon the cover adapted lo frictionally fit within said seat, and a bead upon the cover adapted to fit within the container, whereby a closed, annular chamber is formed, and a gasket adapted to be compressed in said chamber when the cover is pressed into the container, and means for retaining the cover in position, said convex seat form ng-the only means for resisting entrance of the cover into the container.

In testimony that we claim the above, We have hereunto subscribed our names.
